BUILDING-WALL COMPOUND.

SPECIFICATION forming part of Letters Patent No. 293,010, dated February5, 1884.

Application filed March :2, 1583. (No model.)

fication, reference being bad therein to the accompanying drawings.

My invention relates to an improvement in building-wallcompounds; and itconsists in a process by which slag (the dross of furnaces) is employedas a substitute for stone and brick, and in. the process of formingfragmentary slag into suitable blocks for this purpose, and

in the molds A, substantially as hereinafter more fully described.

In carrying out my invention I take three parts of the slag of furnacesand one part of mortar, the mortar being made of one part lime and threeand one-half parts of sand and one and one-half part of water, and thismortar I combine in a suitable proportion to permeate the mass with acementing-mortar made of one pint of alkaline solution of flint, tenpints of sand, one pint of clay, and one pint of powdered flint. I thentake this mass and cast it into rectangular-or cubical blocks by placingit into suitably-constructed molds. The blocks are then removed from themolds and dried. The materials thus combined produce a very hard andvaluable building material at little cost.

In the drawings, Figure 1 is a plan view, and Figs. 2 and 3 are detailviews.

The mold A is rectangular, and adapted for molding the compound intoblocks or bricks.

,The lateral wallB of the mold is rigidly sei cured to the bot-tom C,and has adjustably affixed thereto the longitudinal sides D and e D bymeans of the hinges E E. The lateral 1 end F is hinged to thelongitudinal wall D, and secured therein the staple h, which projectsthrough the slot'of hinged hasp Gr,- secured to the longitudinal wall D,the parts being held together by pin 1?, as shown.

The partitions H and h are removably inserted into grooves formed in thebottom of the mold, and the longitudinal partitions h are recessed at a,to receivathe transverse partitions H, in order that the partitions maybe readily displaced in removing the molded blocks; and to this end thewalls B, D, D, and F are hinged together and secured by the hinged haspsG.

What I claim, and desire to secure by Let ters Patent, is-

1. A building material composed of three parts of furnace-slag and onepart of mortar made of lime, sand, and water, and combined in suitableproportions with an additional cementing-mortar made of powdered flint,a1= kaline solution of flint, sand, and clay, substantially asdescribed.

2. The combination of the mold-bottom C, 65 partitions H and h, walls B,D, D, and F, and hinged hasp G, substantially as shown,

and for" the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
